Analysis of gas transport in high-frequency ventilation.
The pendelluft effect on gas transport and exchange in high-frequency ventilation was investigated by using a simple computational model, in which each pendelluft zone extending over lower generations of airways consists of two branches performing asynchronous motion. The calculated results show that the gas exchange is markedly improved by the pendelluft when the sloshing of flow is generated between neighboring airways.
